Taher engineering offers flexible gear couplings, which have been designed to provide efficient mechanical power transmission capable of both high loads and high speed. These couplings accommodate angular offset or combined angular offset misalignment to fair extent without under strain on shaft and bearings and permit free to each shaft. They offer greatest reliability due to up-to-date design and careful manufacturing ensure economical weight and dimensions with low moments of inertia; and long service life with minimum maintenance. Construction: eagle flexible gear coupling consist of two toothed hubs, two flanged sleeves with internal teeth, made out of en9/c55 steel. The flanged sleeves are identical and interchangeable and are connected with each other by means of close tolerance bolts. For lubrication, plugs are provided for filling oil/greases. The use of `o` rings is made for sealing of oil/grease.
